Application filed December 23, 1910. Serial No. 598,921.

T 0 all whom it may concern:

Be it known that we, JOHN C. KREMER and Axsnnr H. Fox, citizens of theUnited States, residing in Philadelphia, Pennsylvania, have inventedcertain Improvements in Fore-Arm Locks for Guns, of which the followingis a specification.

The object of our invention is to provide a simple and efiectivefastener for securing the fore arm of a gun, particularly of the classknown as break down breech loading guns In the accompanying drawing:-Figure l, is a side view of sufficient of a gun, with the fore arm insection, on the line 1-1, Fig. 2, to illustrate our invention; Fig. 2,is a sectional plan view on the line 22, Fig. 1; Fig. 3, is a transversesectional view on the line 3-3, Fig. 1; Fig. 4, is a perspective view ofthe fore arm iron; Fig. 5 is a detached, perspective view of the slidinglatch bolt, and Fig. 6, is asectional perspective view of the barrels ofthe gun illustrating the lug which is engaged by the bolt.

A is the breech frame.

BB are the barrels of a double barreled shot gun, in the presentinstance hinged at a to the breech frame.

C is the fore arm consisting of the fore arm iron D and the wooden bodysection C, which is secured to the iron in any suitable manner, in thepresent instance by a screw c. The fore arm iron is shaped to accuratelylit the hinged portion of the breech frame, as well as the under side ofthe barrel sec tion of the gun. The iron D is recessed at 2' for thepassage of the lug b and the wooden section 0' is recessed to receivethe lug b and the depending portions of the iron D. The lug Z) isnotched at b to receivethe latch bolt E, which is carried by the forearm iron D. The latch bolt E is made in the form of an H, Fig. 5, havingside portions 6-6, which travel in guideways (Z, depending from the forearm iron D. The guides (Z are closed at each end, as illustrated in Fig.i, so as to make the part substantial and to provide a rigid support forthe latch bolt E.

Mounted on a pin carried by the forward end of the latch bolt E is aroller 6 and mounted between the cross member of the latch bolt and atransverse pin d on the fore arm iron D is a spring F, which tends toforce the latch bolt forward, but which will yield under pressure. Thespring is confined laterally by the depending portions (Z forming theguideway and vertically by the top of the iron D and the web (Z extending from one depending portion (Z to the other. The notched face of thelug b is beveled at b so as to cause the latch bolt to be pushed back asthe fore arm is being placed in position and as soon as the rollerpasses the projecting portion 6 of the lug, it moves forward into thenotch b, retaining the fore arm in posit-ion. The inclined wall of thenotch causes the fore arm to hug the barrel closely so as to preventrattling. Furthermore, as the latch is between the hinge a and the lugb, the fore arm iron is pressed hard against the pivot portion of thebreech frame, taking up any slack due to the wear of the parts so thatthe arm is always tightly attached to the gun when in position. We alsoprovide a neat fit between the face 2" of the fore arm iron and theportion 9 of the lug; the parts being preferably curved as shown, so asto make an accurate fit at this point.

Thus it will be seen by the above construction that a very simple andeffective fastening is provided for securing the fore arm to the gun andthat the wear will be taken up, preventing rattling, which is a commonoccurrence in guns-after being used for any great length of time.

In applying the fore arm to the gun, all that is necessary is to firstplace the butt end of the fore arm against the front end of the breechframe, turning it on the breech frame as a pivot and when the latchreaches the bevel portion of the lug, the spring will be compressed andas soon as the roller passes the projecting portion or high point on thelug, it will spring back of the said portion and thus retain the forearm in posit-ion. The fore arm can be readily removed by simply pullingon the outer end of the fore arm, using the end of the breech frame as apivot and the inclined surface of the notch in the lug will allow theroller to be pressed back against the pressure of the spring when forceis applied and as soon as the roller passes the projecting portion 6 orhigh point of the lug, the fore arm is free.

We claim: I

1. The combination in a gun, of a breech piece, a barrel section pivotedthereto having a depending lug, the lug having a notched face, a forearm consisting of a fore arm iron and a wooden section secured thereto,said fore arm iron being slot-ted at each side to form guides, arectangular latch bolt extending into the slots and adapted to theguides, a loosely mounted roller carried by the outer end of the latchbolt,- and a spring mounted in the fore arm iron and bearing against therear of the latch bolt.

2. The combination in a gun, of a breech frame, a barrel section pivotedthere-to, said barrel section having a depending lug, with a notchedface, a fore arm consisting of a body section and an iron securedthereto and shaped to fit the end of the breech section, said ironhaving a depending portion,

with longitudinal slots therein, a latch bolt in the form of an H, aloosely mounted roller carried by the latch bolt, and a spring mountedbetween the cross member of the latch bolt. and a pin on the fore armiron, the said roller engaging the notched face of the barrel lug whenthe fore arm is in position.

In testimony whereof, we have signed our names to this specification, inthe presence of two subscribing witnesses.
